EPA maintains a series of web guides to all aspects of green infrastructure, from planning to funding and long-term maintenance. Especially useful to determine where and how green infrastructure and urban forestry can meet federal and state rules for stormwater management. Includes many case studies, tools and calculators.
The National Association of Regional Councils provides an up-to-date directory of regional planning organizations. Many are organized into state associations of RPOs.
Philadelphia, long considered a pioneer in green infrastructure and water, maintains a web site that describes their plan, connects to other City goals, provides comprehensive monitoring and progress reporting.

Montgomery County’s Department of Environmental Protection (DEP) present an evaluation of the current MS4 permits. After addressing all parts of the permit they summarize lessons learned. They found that the time required to build an effective restoration program is mismatched by the current 5 year MS4 cycle. Adaptive management approach should be used when administering the MS4. They believe there is a lot more that needs to be understood regarding the effectiveness of practices to improve water quality and how to make programs more cost-effective. The would like to design a program to better evaluate the effectiveness of the State’s stormwater design manual best management practices (green infrastructure). The DEP asserts there needs to be more documentation of the success of Environmental Site Design beyond stream channel morphology.
This model ordinance addresses post-development stormwater management requirements for new development and redevelopment in a community. The ordinance defines requirements for a post development stormwater management plan, which is required in order to undertake land development activities. This plan contains the details of how the development will address post-development stormwater runoff quality and quantity impacts resulting from the permanent alteration of the character and hydrology of the land surface as well as the nonpoint source pollution from land use activities. The ordinance also outlines the water quantity and quality performance criteria for managing this runoff and specifies local requirements for the use of structural stormwater controls and nonstructural practices, in order to protect public health and safety, protection of public and private property and infrastructure, and environmental protection. Ongoing long-term inspection and maintenance provisions are provided.
The EPA website is designed to assist municipalities in growing green infrastructure throughout the built environment. The website features a Municipal Handbook provides local governments step-by-step material on growing green infrastructure in their communities, with chapters on funding options, retrofit policies, green streets, rainwater harvesting policies, and incentive mechanisms. The website also contains a series of EPA policy guide publications for Smart Growth and water resources protection that can be used by municipalities looking to innovate their policies concerning green infrastructure. Finally a policy tool kit features communication and program evaluation tools that are designed to help local governments effectively promote green infrastructure.
